Power Management in the BIOS
If your computer stays idle for a certain amount of time, your system BIOS switches the system from Full Power Mode to
Suspend Mode in order to reduce power consumption.
In Suspend Mode, graphics, the processor and hard disks are stopped. Any user event, such as from the mouse or
keyboard, will cause the system to resume to Full Power Mode within a few seconds.
Other events may also wake up the system: a daily alarm clock (for a scheduled backup), a ring on an external modem,
an IRQ signal sent by an expansion card (modem, network card, etc.).
To customize the power management settings though the HP
Setup
program, use the

keys to move along the
top of the main menu bar to the Power Menu. The item is then highlighted and displays the available power management

You will be able to set the delay before the system can automatically enter Suspend Mode, and also specify the events
which will make the computer wake up.
In most cases, default settings should be appropriate. However, you may need to configure the IRQs which will be
monitored in accordance with your system components (additional network card or modem ...). For this, select the field
